This module allows for the connection of a two-wire monitored sensing edge to be connected to the ODC STB terminals. Compatible for use on Miller Edge electronic two-wire monitored edge models ME, MT and MU.

Transmitters

The RSX® and RHX® operators feature a built-in Radio Receiver System that can store up to 250 transmitters, giving the customer the ability to identify which transmitters have been operating the door. Radio transmitters may be single-button, two-button, three-button, four-button, or Open/Close/Stop. They are easily programmed or erased using the LCD display. The patented CodeDodger® technology cycles between 315 and 390 MHz with the touch of a button.
